Kleeblattschadel anomaly and partial trisomy for chromosome 13 (47,XY,+der(13),t(3,13)(q24;

Abstract
A case of partial trisomy involving the proximal segment of the long arm of chromosome 13 is reported. Kleeblattschaedel anomaly was one of the many anomalies found in conjunction with this syndrome in this infant. The cytogenetic classification of the extra partial chromosome was based on trypsin-Giemsa banding patterns and a paternal translocation involving chromosomes 3 and 13.
